Oleg Dubov has studied Chemistry (bachelor degree) in St-Petersburg State University, Russia, where he developed the thesis “Synthesis and characterization of a novel polyacrylic chelating ion-exchange fiber material for heavy metals removal from water”. After her bachelor degree, he takes a master in Global Management of Innovation and Technology at Lappeenranta University of Technology, Finland. His master thesis was about the profitability of recycling of small electronic devices for recovery of critical materials. Dubov has a seven years work experience in different companies, such as the BTP group of companies. The group of companies includes Swiss, Russian, Finnish, Italian and Chinese engineering, production and marketing enterprises. As a head of R&D department, he was in charge for all the innovative and technologically challenging projects.

Project: Carbon-based catalytic membrane reactors for the treatment of emerging and recalcitrant water contaminants through Fenton-like processes

The main purpose of the requested project is developing a new family of carbon-based membrane reactors to be applied for the treatment of wastewater containing emergent or recalcitrant contaminants. These new reactors will be used for the oxidation using hydrogen peroxide catalyzed with supported zero valent iron (H2O2/ZVI). The technologies to be developed are based on the coupling, through selective ceramic membranes (of nano- or ultrafiltration) used as support for a deposited carbonaceous layer possessing catalytic activity. In the first phase, the carbon membrane synthesis methodology will be developed in order to obtain a thin carbon layer over the ceramic filtration elements. Starting from a polymeric precursor, the layer will be created by controlled carbonation and the main variables affecting the process will be optimized to get defect-free carbon layers. In the second phase, ZVI in form of nano-clusters will be deposited over the carbonaceous layer, thus imparting catalytic activity. The presence of ZVI allows accelerating the Fenton-like oxidation -using hydrogen peroxide, as ferrous cations are continuously generated, so a higher production of hydroxyl radicals is expected to be reached, and consequently an enhanced reaction rate.
